        3,
        12
      ],
      [

        13
      ]
    ]
  }
}

Requires:

{
  "or": [
    "canUseFrozenEnemies",
    "HiJump",
    "canSpringBallJumpMidAir"

Dev note: Here Samus spawns at or slightly inside the left wall; the additional requirements are for getting up to the platform below the door. FIXME: end at a new node below the platform; a flash suit is another way to get up.
